Science Space Exploration megathread - Page 355

**DaFace** · 07:17 AM

Since a number of cool things are happening in space exploration these days, we'll widen the scope of this thread a smidge. Conversation about all things space exploration are welcome, whether it be from NASA, SpaceX, ULA, Blue Origin, or anyone else. Chances are most of the discussion will still be about SpaceX since they love to make things public and fun, but nothing's off limits. I'll eventually get around to modifying the OP to include resources for other companies too, but in the meantime, feel free to post any cool stuff you run across.

Space discussions tend to get a little bogged down in jargon, so here's a list of terms you might encounter. (Others, please let me know of others that should be added.)

ASDS - Autonomous Spaceport Droneship - The "barges" that they sometimes land rockets on.
Dragon - The cone-shaped capsule that sits at the top of the rocket for ISS-bound launches that holds the cargo (or, in the future, humans).
F9 - Falcon 9, the name of the rocket itself.
FH - Falcon Heavy, the three-booster version.
GTO - Geosynchronous Transfer Orbit, a type of orbit that will eventually result in the satellite orbiting the earth as it turns so that it seems to be in the same spot from the ground (such as DirecTV or Dish satellites). These types of launches are particularly challenging because they require a lot of power to get them into the right orbit, leaving very little fuel left for landing.
HIF - Horizontal Integration Facility - the building near the launch pad where they put all of the pieces of the rocket together before rolling it out to the pad.
ISS - The International Space Station
JRTI - Just Read The Instructions, the name of the "barge" that they land on for west-coast launches.
LEO - Low Earth Orbit, a fairly low orbit shared by many satellites and ISS. These launches usually require less power to achieve the proper orbit, so the first stage can often be landed back on land rather than on a drone ship.
LZ1 - Landing Zone 1, basically a big open slab of concrete at Cape Canaveral where the first stage will attempt to land (for some launches).
NET - No Earlier Than, basically the date they're hoping to launch, but rocket launches have a tendency of getting delayed.
OCISLY - Of Course I Still Love You, the name of the "barge" that they land on for east-coast launches.
RTLS - Return to Landing Site, a mission where the first stage comes back and lands at LZ1.
Starship - SpaceX's next-generation rocket (and spacecraft) that will hopefully one day take us to Mars. Starship is the "second stage" that will carry cargo or people, but also refers to the whole system. (It's confusing, but think of it like the Space Shuttle, which was both the shuttle itself and the entire launch system.)
Super Heavy - The giant booster that will carry Starship to space.

Hope it's not another fake.

SpaceX =/= Elon. I'd be surprised if SpaceX posted something fake.

Now targeting Monday, December 11 for Falcon Heavy’s launch of the USSF-52 mission, with weather conditions forecasted to improve to 70% favorable for liftoff on Monday night. The team will use the time to complete additional pre-launch check outs → https://t.co/bJFjLCiTbK pic.twitter.com/OsQ6bjWwxK
— SpaceX (@SpaceX) December 10, 2023

SpaceX is targeting Monday, December 11 at 8:14 p.m. ET for Falcon Heavy’s launch of the USSF-52 mission to orbit from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. A backup launch opportunity is available during the same time on Tuesday, December 12.

A live webcast of this mission will begin on X @SpaceX about 15 minutes prior to liftoff. Watch live.

This will be the fifth launch and landing of these Falcon Heavy side boosters, which previously supported USSF-44, USSF-67, Hughes JUPTER 3, and NASA’s Psyche mission. Following booster separation, Falcon Heavy’s two side boosters will land on SpaceX’s Landing Zones 1 and 2 (LZ-1 and LZ-2) at Cape Canaveral Space Force Station in Florida.

Standing down from tonight’s Falcon Heavy launch due to a ground side issue; vehicle and payload remain healthy. Team is resetting for the next launch opportunity of the USSF-52 mission, which is no earlier than tomorrow night.

SpaceX's powerful Falcon Heavy rocket will fly again before the end of the year, if all goes according to plan.

SpaceX is now targeting Dec. 28 for the launch of the U.S. Space Force's X-37B space plane, which will fly atop a Falcon Heavy from NASA’s Kennedy Space Center in Florida.

In the not too distant future, we should see this method used for Starlink satellite deployment in orbit.

Booster 10 static fire test could be conducted as soon as Thursday. Integrated Flight Test 3 could occur within a month or two. Exciting to see the processes gaining steam.

**DaFace** · 12-21-2023, 10:07 AM

Nice to see the pace accelerating. Guess it helps when you don't blow the launch pad to bits.

Imagine needing to build a new airport after every flight...

**DaFace** · 12-25-2023, 08:53 PM

This is actually kind of sad. RIP 1058.

During transport back to Port early this morning, the booster tipped over on the droneship due to high winds and waves. Newer Falcon boosters have upgraded landing legs with the capability to self-level and mitigate this type of issue

The development of rotating detonation motors has potential to improve capabilities, especially in space. Potentially a 25% improvement in efficiency. And they’re pretty cool.
